Abstract: Provided is a separation and recovery apparatus for continuously separating and recovering, from a resin mixture containing a resin containing a hydrolyzable polymer and a resin containing a nonhydrolyzable polymer, a hydrolytic component a of the hydrolyzable polymer A and the nonhydrolyzable polymer B, the apparatus including: a crushing unit that crushes the resin mixture a melting/discharging unit that melts a crushed product obtained by the crushing unit to form a fluid and discharges the fluid at a high pressure; and a hydrothermal reaction treatment unit that continuously subjects the fluid discharged from the melting/discharging unit to a hydrothermal reaction treatment, wherein, in the melting/discharging unit, the hydrolyzable polymer A is hydrolyzed, and the hydrolytic component a thereof is dissolved and transferred into water permeating a sintered alloy diaphragm, thereby separating the nonhydrolyzable polymer B.

Abstract: Surface-coated aluminum oxide nanoparticles capable of being uniformly blended into polycarbonate resin in a good dispersed state while maintaining a molecular weight of the polycarbonate resin at a specific level or more. Surfaces of the surface-coated aluminum oxide nanoparticles are coated with a dispersant and a silylation reagent. In a case where a monochromated Al-K? ray is irradiated onto a sample surface by using an X-ray photoelectron spectroscope, when a surface element composition is calculated from an obtained photoelectron peak area, contents (atm %) of nitrogen atoms, thiol-derived sulfur atoms, and halogen atoms in the surface-coated aluminum oxide nanoparticles are individually 2 or less, and when the surface element composition is calculated from obtained photoelectron peak areas of Al2p and Si2s, a concentration (mol %) of silicon atoms with respect to aluminum atoms is 0.05 to 30.
